摘要

设计制作了染料掺杂手性向列相液晶器件，研究了其随机激光辐射行为。均匀混合激光染料DCM和PM597、手性剂S-811、向列相液晶TEB30A，注入无摩擦取向的40

m液晶盒，制成焦锥织构态的手性向列相液晶激光器件。采用固体Nd：YAG倍频532 nm波长的脉冲激光作为抽运光泵浦样品。掺杂激光染料PM597和DCM的液晶器件分别在575～588 nm和600～620 nm范围显示了尖锐、分立的随机激光辐射峰，线宽约为0.3 nm。探测了器件在不同方向上的激光辐射谱，在与样品表面夹角约为45°～150°的范围内均能探测到随机激光。在器件中，手性向列相液晶焦锥织构态对光的强散射作用是随机激光产生的主要原因。

Abstract

A device of dye-doped chiral-nematic liquid crystal laser is prepared

and the random laser mechanism is analyzed. A focal conic state is achieved after mixing laser dyes DCM and PM597. Chiral compound S-811 and nematic liquid crystal TEB30A are infused into 40

m cells with no rubbing treatment

respectively. A Nd:YAG pulsed solid-state laser with a wavelength of 532 nm is used as pump source. Both cells emit a discrete and sharp random laser with a line-width of 0.3 nm. The laser from the PM597 doped cell has a wavelength region of 575～588 nm

and the laser from the DCM doped cell has a wavelength region of 600～620 nm. The random laser can be detected in a fan-shaped region with an angle from 45° to 150° to the cell surface. In the device

the strong scattering of chiral conical texture of liquid crystal in chiral nematic liquid crystal is the main reason of random lasing.
